Faxon Firearms - Adjustable .750" Low Profile Gas Block

The Faxon Adjustable .750" Low Profile Gas Block enhances AR-15 performance by providing precise control over gas flow. This is achieved through its 14 tactile settings, allowing users to adjust from fully open to fully closed. Such control can significantly reduce recoil and improve cycling reliability, especially when using different ammunition types or when a suppressor is attached. The innovative design ensures the adjustment screw remains free from carbon fouling, maintaining easy adjustments even after extensive use.

The Faxon Adjustable Gas Block's design is unique due to its patent-pending mechanism where the gas tube is pinned to an adjustment plate. This allows the adjustment screw to slide the plate to meter gas flow without exposure to carbon fouling. This design ensures that the adjustment screw remains operable even after thousands of rounds, providing consistent performance whether the firearm is suppressed or not.

The Faxon Adjustable Gas Block is constructed from 4140 chromoly steel, known for its strength and durability. It is finished with a flash nitride coating, which enhances its resistance to corrosion and wear. This combination of materials ensures that the gas block can withstand the rigors of extensive use and harsh environmental conditions, making it a reliable component for any AR build.

The low-profile design of the Faxon Gas Block allows it to fit under most free-float handguards. This is particularly beneficial for AR builds that prioritize a sleek and streamlined appearance. Additionally, the low-profile nature does not compromise performance, as it still offers full adjustability and durability. This makes it an excellent choice for those looking to maintain a clean look while optimizing their firearm's gas system.

Yes, the Faxon Adjustable Gas Block is compatible with various gas system lengths including pistol, carbine, mid, and rifle. This versatility makes it suitable for a wide range of AR configurations. Whether you're building a compact pistol or a full-length rifle, this gas block can be adjusted to optimize performance across different setups, ensuring reliable operation regardless of the system length.

The adjustment mechanism of the Faxon Adjustable Gas Block involves a screw that slides an adjustment plate to meter gas flow. This design is protected from carbon fouling, ensuring that the screw remains easy to turn even after extensive use. The 14 tactile settings provide precise control, allowing users to fine-tune their firearm's gas system for optimal performance.

The Faxon Gas Block is designed to minimize the impact of carbon fouling on its adjustment mechanism. By pinning the gas tube to an adjustment plate, the screw that meters gas flow is not directly exposed to carbon buildup. This ensures that adjustments remain easy and consistent, even after firing thousands of rounds. This feature is especially beneficial for those who frequently shoot suppressed, where carbon fouling can be more pronounced.

Adjusting the Faxon Adjustable Gas Block requires a 3/32" hex key or a flat screwdriver. These common tools make it easy to make on-the-fly adjustments in the field or at the range. The accessibility of these tools ensures that you can maintain optimal performance without needing specialized equipment.

Yes, the Faxon Adjustable Gas Block is compatible with both AR-15 and AR-10 platforms. It is designed to fit any direct-impingement AR with a .750" journal, making it a versatile choice for various builds. This compatibility allows users to enjoy the benefits of adjustable gas flow across different calibers and configurations.

The Faxon Adjustable Gas Block measures 1.000" in length, with a width of .639" and an overall height of 1.350". The body diameter around the journal is .899", which allows it to fit snugly under most free-float handguards. These dimensions ensure that it provides a low-profile fit without sacrificing the ability to adjust gas flow effectively.
